The man, Aleksey Germash, 53, has been with the U.S. Postal Service for 16 years, before his bosses received a tip about a parked auto with 20 bags of undelivered mail, close to the Dyker Heights, Brooklyn post office to which was recently assigned.
Among the mail trove found in Germash's Nissan Pathfinder, his apartment and his work locker was a letter from 2005, according to Brooklyn federal prosecutors.
A NY mailman has been arrested for stockpiling thousands of pieces of undelivered mail, spanning nearly 15 years.
Khloe Kardashian 'learned so much' about motherhood from her sisters
The basketball player has already come crawling on his knees asking for forgiveness, and Khloe has not yet broken up with him. Days before Khloe was due to give birth, Tristan was reportedly spotting kissing a brunette at a roof top bar in Manhattan.
Investigators say Germash said he took mail to his auto and apartment, and that he told them he "made sure to deliver the important mail".
Cops also say that he had 1,000 undelivered pieces of mail in his locker, 10,000 in his auto, and 6,000 in his apartment.
His arrest comes after a recent assignment to the Dyker Heights Post Office in Brooklyn.
A Brooklyn postal worker was arrested after 17,000 pieces of undelivered mail were found in his vehicle, apartment and home, authorities said. A Philadelphia postal worker who was found in 2015 to have retained 22,000 postal items was only charged with obstruction of mail in 2015-a misdemeanor punishable by no more than six months in jail.
Germash appeared in Brooklyn federal court on Thursday - wearing his postal uniform - and was released on $25,000 bail.
During an interview with agents from the USPS Office of Inspector General, Germash said he was "overwhelmed by the amount of mail that he had to deliver".
